Kapangidwe ka matope osakaniza owuma kumadalira mtundu wa ntchito yomwe imapangidwira. Nthawi zambiri, kapangidwe ka matope osakaniza owuma kumaphatikizapo zigawo izi:
Simenti: Simenti ndiyo imamangira matope owuma ndipo nthawi zambiri imakhala yodula kwambiri. Nthawi zambiri amapangidwa ndi simenti ya Portland, yomwe imaphatikizapo calcium, silika, alumina, ndi iron oxide. Kuchuluka kwa simenti yogwiritsidwa ntchito mumatope osakaniza owuma kumasiyana malinga ndi momwe matopewo akugwirira ntchito komanso mphamvu yomwe mukufuna.
Mchenga: Mchenga ndi gawo lachiwiri lofunika kwambiri mumatope osakaniza owuma. Amagwiritsidwa ntchito kuti apereke zambiri komanso mphamvu kumatope. Kukula ndi mtundu wa mchenga womwe umagwiritsidwa ntchito zimatengera momwe matopewo amagwirira ntchito komanso mphamvu yomwe mukufuna.
Laimu: Laimu amawonjezeredwa kumatope osakaniza kuti awonjezere kugwira ntchito kwake ndikuchepetsa kuchepa. Zimathandizanso kuchepetsa kuchuluka kwa madzi ofunikira pakusakaniza komanso kumapangitsa kuti matope azitha kulumikizana ndi gawo lapansi.
Zosungira Madzi: Zosungira madziMa cellulose ethersamawonjezeredwa ku matope osakaniza owuma kuti athandize kusunga chinyezi ndi kuchepetsa kuchuluka kwa madzi ofunikira kusakaniza. Izi nthawi zambiri zimapangidwa ndi ma polima kapena zinthu zina zopangira.
